Zarlink Semiconductor has demonstrated the transmission of circuit-switched traffic over a WiMAX connection using circuit emulation services over packet (CESoP). The tests used Wavesat's WiMAX chip and Zarlink's CeSoP processor. Zarlink said that by using its CESoP technology in both the base station and subscriber WiMAX equipment, circuit-switched traffic together with associated timing and signaling information can be converted into Ethernet packets and seamlessly carried across the WiMax network. http://cesop.zarlink.com/http://www.wavesat.com
